Check Digit Verification of cas no

The CAS Registry Mumber 1567374-03-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,7,3,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1567374-03:
(9*1)+(8*5)+(7*6)+(6*7)+(5*3)+(4*7)+(3*4)+(2*0)+(1*3)=191
191 % 10 = 1
So 1567374-03-1 is a valid CAS Registry Number.

Anodic cyclization of dimethyl 2-(5-aryl-5-oxopentyl)malonates into the corresponding dimethyl 2-aroylcyclopentane-1,1-dicarboxylates

Okimoto, Mitsuhiro,Yamamori, Haruki,Hoshi, Masayuki,Yoshida, Takashi

, p. 1299 - 1302 (2014/03/21)

A wide range of dimethyl 2-(5-aryl-5-oxopentyl)malonates was electrooxidized in methanol, in the presence of catalytic amount of potassium iodide, to give the corresponding dimethyl 2-aroylcyclopentane-1,1- dicarboxylates in high yields. The reactions were carried out under extremely mild reaction conditions, in which the optimal amount of electrolytic current ranged from 2.24 to 2.35 Fmol-1. The reaction presumably proceeded via a two-electron oxidation process, in which iodide ions played an important role as the electron carrier between the anode and the substrate.
